linear combination of atomic orbitals by wave function

According to LCAO method, the orbitals are formed by the linear combination (addition or subtraction) of atomic orbitals of the atoms, which form the molecule. This theory is applicable to hydrogen molecule as follows. Consider that ..

Molecular Orbital Theory - Molecular orbital theory was proposed by F. Hund and R.S. Mulliken in 1932. The basic idea of molecular orbital theory is that atomic orbitals of individual atoms combine to form molecular orbitals..

Physical Significance of Wave Function - In the physical sense, y gives the amplitude of the wave associated with the electron. It is known that in case of light waves, the square of the amplitude of the wave at a point is proportional to the intens..

In the physical sense, y gives the amplitude of the wave associated with the electron. It is known that in case of light waves, the square of the amplitude of the wave at a point is proportional to the intensity of light. Extending the same concept to electron wav..

Concept of Orbital - According to wave mechanics, we cannot simply say that the electron exists at a particular point but we talk about certain regions in space around the nucleus where the probability of finding the electron is maximum. Such regions are expressed by mathematica..

Bonding MO Antibonding MO Bonding molecular orbital is formed by the addition of overlapping of atomic orbitals. The wave function of the bonding MO may be written as :ψ(MO)= ψ A + ψ B Antibonding molecular orbital..

. It is abbreviated Z. Mass number is defined as the sum of the number of protons and neutrons in the nucleus of the atom. It is denoted by 'A'. Atoms of the same element having same atomic number but different mass numbers are called isotopes. Isotopes show similar ch..

When the two 2p z orbitals are brought closer along the internuclear axis, they overlap head on forming a-bond. When the two orbitals overlap by the addition of electron waves (when + + lobes overlap), bonding molecular orbital is formed. This may be design..

In alcohol, the oxygen of the -OH group is attached to sp 3 hybridized carbon by a sigma ( s ) bond formed by the overlap of sp 3 hybrid orbital of carbon with an sp 3 hybrid orbital of oxygen. in alcohols is slightly less than the tetrahedral angle (109 o 28') In phenols the -O..

Schrodinger wave equation, when solved for hydrogen atom gives mathematical Y functions, which describe the allowed energy states in an atom. It is observed that physical meaningful solutions required three constants n, l and m, which are called quantum numbe..
